Depth of field
Portraits or still-life photos mostly acclaimed by people are the ones on 
which the background is out of focus so the subject looks pronounced. 
Depending on the focused areas, a photo can be blurred or sharpened. 
This is called ‘a low DOF’ or ‘a high DOF’.
The depth of field is the focused area around the subject. Therefore, 
a small DOF signifies that the focused area is narrow and a large DOF 
means the focused area is wide.
A photo with a small DOF, which stresses the subject and makes the 
rest of it blurred, can be obtained by using a telescope lens or selecting 
a low aperture value. Conversely, a photo with a large DOF which 
shows all the elements on the photo sharply focused can be achieved 
by using a wide angle lens or selecting a high aperture value.

What controls out-of-focus effects?
DOF depends on aperture value
The wider the aperture is (namely the lower the aperture value), the 
lower the DOF becomes. Under the condition where the other values 
including shutter speed and ISO sensitivity are equal, a low aperture 
value leads to a photo with a low DOF.

DOF depends on focal length
The longer the focal length is, the lower the DOF gets. A telescope lens\
 
with a longer focal length than a telescope lens with a short focal leng\
th 
is better to capture a photo of a low DOF.

telescope lens
DOF depends on the distance between the subject and 
the camera
The shorter the distance between the subject and the camera is, the 
lower the DOF gets. Therefore, taking a photo close to a subject can 
result in a photo of low DOF.

DOF preview
You can use the Custom button to get an idea of what your shot will 
look like before shooting. When you press the button, the camera 
adjusts the aperture to the predefined settings and shows the results on 
the screen. Set the function of the Custom button to Optical Preview.

Composition
It is fun to capture a photo of the beauty of world with a camera. No 
matter how the world is beautiful, however, a poor composition cannot 
capture the beauty of it.
When it comes to composition, it is very important to prioritize subject\
s. 
Composition in photography means arranging objects in a photo. 
Usually, abiding by the rule of thirds leads to a good composition.
Rule of Thirds
To use the rule of thirds, divide the image into a 3x3 pattern of equal 
rectangles.
To compose photos that best emphasize the subject, make sure the 
subject is located at one of the corners of the center rectangle.

Concepts in Photography
Using the rule of thirds will create photos with stable and compelling 
compositions. Below are a few examples.Photos with two subjects
If your subject is in one corner of the photo, it creates an unbalanced 
composition. You can stabilize the photo by capturing a second subject 
in the opposite corner to balance the weight of the photo.

When taking landscape photos, centering the horizon will create an 
unbalanced effect. Give more weight to the photo by moving the 
horizon up or down.

Flash
Light is one of the most important components in photography. It’s 
not easy, however, to have an enough amount of light anytime and 
anywhere. Making use of a flash allows you to optimize light settings 
and create a variety of effects.
Flash, also known as strobe or speed light, helps to create adequate 
exposure in low-light conditions. It is also useful in light-abundant 
situations. For example, flash can be used in compensating the 
exposure of a subject’s shadow or capturing clearly both the subject 
and the background in backlit conditions.

Flash guide number
The model number of a flash refers to the flash’s power, and the 
maximum amount of light created is represented by a value known 
as a “guide number.” The bigger the guide number, the more light is 
emitted from the flash. The guide number is achieved by multiplying the 
distance from the flash to the subject and the aperture value when the 
ISO sensitivity is set to 100.
Guide number = Flash to Subject Distance X Aperture value
Aperture value = Guide number / Flash to Subject Distance
Flash to Subject Distance = Guide number / Aperture value
Therefore, if you know the guide number of a flash, you can estimate an 
optimum flash to subject distance when setting the flash manually. For 
example, if a flash has a guide number of GN 20 and is 4 meters away 
from the subject, the optimal aperture value is F5.0.

Bounce Photography
Bounce photography refers to the method of bouncing light off of 
the ceiling or walls so that the light spreads evenly over the subject. 
Normally, photos captured with flash may appear unnatural and cast 
shadows. Subjects in photos captured with bounce photography cast 
no shadows and look smooth due to evenly spread light.
